Both endpoints use
https://catalog.basaltic.sh. Requests are limited to 100
per minute per endpoint and client IP. A 429 response means that limit was
reached; wait before retrying.
Discovering a region does not grant permission to create resources there. Each
product API enforces its own IAM actions, account access, quotas, and placement
requirements. Catalog has no public write endpoint.
See Regions and endpoints for lifecycle fields and global versus
regional service addresses.
